New French CEPT paper still seeks 144-146 MHz for Aeronautical

CEPT LogoThe French administration has renewed its attack on the Amateur Radio 144-146 MHz band ahead of a key CEPT ECC CPG meeting in Ankara, August 26-30.

In a paper to be considered at the conference the French Administration says it is not at this time seeking Primary status for the Aeronautical Mobile Service in 144-146, however, their intent is still that the Aeronautical Mobile Service should share the amateur 2m band.

It is clear where such sharing would inevitably lead, amateur operation in the band would only be tolerated if there were no interference to Aeronautical Mobile. Radio Amateurs might be subject to heavy restriction and low EIRP limits.

We can get on idea of France’s long term intent for 144 MHz from their attitude to the 1240-1300 MHz band. It was initially said the Galileo constellation could amicably share this allocation and amateur operation could continue but now France says “unregulated use of the band 1240-1300 MHz by the amateur service is a serious source of harmful interference to RNSS receivers.”

144-146 MHz WebSDR at Goonhilly now available

144-146 MHz WebSDR at Goonhilly now available

Goonhilly 144 MHz WebSDRGoonhilly 144 MHz WebSDR

AMSAT-UK and BATC have announced the availability of a new 144-146 MHz Web-based Software Defined Radio installation at Goonhilly.

WebSDR Antenna top rightWebSDR Antenna top right

This is being provided in collaboration with Goonhilly Earth Station where it is kindly hosted alongside the existing receiving equipment for the amateur radio transponders on the Qatar-Oscar-100 (QO-100 / Es’hail-2) geostationary satellite.

It shares the same Turnstile antenna that is used for the reception of the AO73, EO88 & JO97 CubeSats.

Being located in the far South West of the UK, it is anticipated the SDR will be useful for early Acquisition of Signal (AOS) of 144 MHz downlinks from amateur satellites and the International Space Station (ISS). Additionally it can be used for reception of tropospheric signals from the south – the Spanish beacon ED1ZAG on 144.403 MHz has been already been heard on the system.

The new 144 MHz band WebSDR is available at https://vhf-goonhilly.batc.org.uk/

The AMSAT-UK / BATC 10 GHz WebSDR for QO-100 is still available at https://eshail.batc.org.uk/

Russian Spacecraft Docking Attempt No Earlier Than Monday

Russian Spacecraft Docking Attempt No Earlier Than Monday

International Space Station Configuration
International Space Station Configuration. Four spaceships are parked at the space station including the SpaceX Dragon cargo craft and Russia’s Progress 73 resupply ship and Soyuz MS-12 and MS-13 crew ships.

An uncrewed Russian Soyuz MS-14 spacecraft is now a safe distance away from the International Space Station following an abort during its final approach for a docking to the Poisk module.

After the cosmonauts on the station aborted an automated docking attempt early Saturday, Russian flight controllers told the crew on the station that early data indicates the issue that prevented its automated docking resides on the station’s side of the so-called KURS automated rendezvous system, not on the Soyuz itself.

The Soyuz is on a safe trajectory above and behind the space station that will bring it in the vicinity of the orbital complex again in 24 hours and 48 hours. Russian flight controllers have indicated the next earliest docking attempt could be Monday morning.

In the meantime, Russian controllers informed Expedition 60 commander Alexey Ovchinin and flight engineer Alexander Skvortsov of the Russian federal space agency Roscosmos they will send instructions to swap the signal amplifier of the station’s KURS docking system and test it before proceeding with another docking attempt.

The Soyuz launched from the Baikonur Cosmodrome in Kazakhstan on Wednesday, Aug. 21, at 11:38 p.m. EDT (8:38 a.m. Aug. 22 Baikonur time) on a test flight to validate the spacecraft’s compatibility with a revamped Soyuz booster rocket.

Uncrewed Russian Spacecraft Aborts Station Approach

Uncrewed Russian Spacecraft Aborts Station Approach

At 1:36 a.m. EDT, Russian cosmonauts issued a command to abort the automated approach of an uncrewed Russian Soyuz spacecraft to the International Space Station after the craft was unable to lock onto its target at the station’s space-facing Poisk module.

The Soyuz MS-14 spacecraft launched from the Baikonur Cosmodrome in Kazakhstan on Wednesday, Aug. 21, at 11:38 p.m. EDT (8:38 a.m. Aug. 22 Baikonur time) on a test flight. It made 34 orbits of Earth en route to its anticipated docking to the station.

Following the abort, the spacecraft backed a safe distance away from the orbital complex while the Russian flight controllers assess the next steps.
